Specication of Letters Patent.

1 Patented Mar. 14, 1911.

application aiea February 25, 1910. serial No. 545,868.

To all whom it may concern:

Be it known that I, BARRY IvoR, .a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certainI new and useful Improvements in Carbdreters, of which the following is a specification.

This invention relates to certain improvements in a device of a somewhat similar character and construction to that shown and described in an application for Letters-Patent, filed byme, on the 13th day of January, 1910, for improvements in carbureters, which application bears Serial Number 537,87 2, and some of the objects of my present invention are sinnlar tothose set forth in the above-mentioned application, but other objects and results will be attained thereby, and the objects, in part, are as follows; yto provide a simple, inexpensive' and efficient carbureter for hydrocarbon engines of various types and for different uses, but more particularly for gasolene engines for operating automobiles; to dispense with the use of the ordinary float valves which are comlnonly employed in carbureters heretofore in general use, the use of which valves is objectionable for the reason said float valves are liable to clog, to be misplaced by the vibrations of the machine, 'and to permit of flooding or undercharging the engine.

Another object 1s to provide a carbureter in which the quantities of air and gasolene or hydrocarbon admitted to the mixing' chamber can be readily and nicely regulated, and the same more thoroughly cornmingled than is ordinarily done, and will v be of such construction and operation as to prevent waste of gasolene or hydrocarbons.

A further object is to provide a pump of an improved construction and operation, which, while more especially intended for use in connection with the other elements of a carbureter, .yet is applicable and may be used for other purposes.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In the accompanying drawings which serve to illustrate the invention :-Figure '1, is a view in side elevationof al carbureter embodying the invention; Fig. 2, is a plan view thereof; Fig. 3, isa central vertical sectional view; ll elevation of the lower portion ofthe casing;

Like numerals of reference, refer to corresponding parts throughoutthe different views of the drawings. a

The reference numeral '20, designates the casing or body of thecarbureter, as a whole,

surface with a packing ring 26, of any suit?,vv Iable material to coact with the valve 24, so

as to form a close joint and also to prevent noise. Extended diametrically across the valve seat 23, is a bar or member 27, which is provided with a central opening 28, for

.the reception of the pump body or cylinder and on each side of said central openingl with an opening 29for the upper portions of rods 30, which are connected at their lower ends .by means of a bar 31, through a central opening in which is extended the lower portion of the pump plunger 32,

which portion is screw-threaded and has lin engagement therewith above the bar 31, a

`nut 33, which may be used for more securely holding the bar 31, in place on the plunger.

As is clearly shown in Fig. 4, of the drawings, the lower portion 22, of the casing is `provided with a series of -openings 34, forl the passage of air and also with a slot 35,

through which is-extended an arm or exten- 45, with which the upper portion of the casf other end a Aconnection 52, which vmay lead y screw 55, the inner end of which is adapted is enlarged as at shown in Fig. 6, and is'lccated withln the' 1 part 22, below thepo'rtion thereof which enthe passage of the mixture tion of the rod 44, just above Vthe extension the supply lof the ,engagingan opening in the upper portion casing. The fitting 61,l is providedoppo- 'site the' extension portion 66, located sion 36, on the periphery of the air regulator 37, which is provided with a serlesv o openings 38, to register with the openlngs 34, 1n the part 22, ofthe easing. The regulator 37, is' preferably segment-al in sha e as gages the aforesaid valve seat. The arm 36, on the regulator 37, is provided with a transverse slot 39, inwhich is located the sleeve nut 40, which receives andengages a screw 41, which is extended upwardly from the arm 36, through a slot 42, in an arm 43, mounted onthe lower portion of a rod 44,l which is journaled on a suitable extension ing is provided.

As shown in Figs. 5, and 7, the arm 36, is provided on one of itsside ed es with an upwardly extended portion 46, 1n which is located. a screw 47, projected in the path of the arm 43, and used to limit the movement thereof in one direction.- This arm is fixed on th-e lower portion of the rod 44, which rod is extended through a hollow extension `45, on the casing 21, and also through a conduit 48, which communicates at one of 4its ends with a neck or reduced portion 49, extended upwardly from thelupper part of the casing and having communication with the mixing chamberthereof. The other end of the conduit or extension 48, may be suitably con'nected to the engine (not shown) and is provided on the rod'44, with a damper 50, of any well known type yto regulate of air and gaso- .lene from the mixing chamber to the engine. Secured at one of its ends :onthe upper por- 48, is a lever 51, which has secured to its to a lever :(:not shown)\used for regulatingy mixture of air land gasolene to the engine. Mounted on the rod 44, above the lever 51, is a yoke 53, which' has in one of its upturned ends 54, a regulating to coact with a cam 56, mounted on the upper end of the rod 44, as'is clearly shown in Fig. 2, of the drawings. Horizontally mounted on the other upturned end 57, of the yoke and movable therewith, is one end of ashaft orrod 58, the other end of which 59, and located in a horizontally disposed cavity 60, of a'tting`61, which has a screw threaded extension l62,

of the neck or reduced portion 49, of the 63, thereon in which the cavity 60, is found, with a horizontal extension`64, in the hollow of which is located an enlarged portion 65, of the rod or shaft`58, which rodor shaft is formed with a tapered l between the enlarge- `jected position by means `rod 73, in screw engagement with the up portion of the enlargement 6 8, of the needle .casing 20,is cylindrical in its 24, is provided with a series ments 59, and 65, as is clearly shown in Fig. 3, of the drawings. The ttin v6,1, has extended vertically. therethroug a needle valve 67, the lower end of which is pointed or conical in shape and is adapted to control the flow of gasolene through the valve seat located in the upper portion'of the pump, as will be upper portion of t 1e needle va ve 67, is preferably enlarged as at 68, and has a transverse opening 69, for the passage of the tapered portion 66, of the valve regulating rod 58, which is normally held in its prokof a spring 70, encircling the same between the enlargement 65, thereon and the cap 71, on the end of the extension 64, within the cavity of which extension said spring is located.

. As is clearly shown in Fig. 3, the fitting 61, is provided on its top with a removable cap 72, throughwhich is extended a screw per valve and extended into the transverse open- .ing 69,' thereof so as to contact with the tapered portion 66, of the valve regulating rod. Around the screw rod 73, is a sprin 74, which has one of its ends seated against the cap 72, and its other end against a nut 75, on said rod above the enlargement 68, of the needle valve. Located in the end of the extension 63, is a set screw 76, the inner end of which is adapted to contact with the outer end of the enlargement 59, so as to restrict its movement in one direction. By reference to Figs. 3, and 9, of the drawings, it will be seen that the upper part 21, ofthe lower portion while its upper part is dome-shaped or contracted upwardl andhas in its upper portiona downwardly 'ared battle 77, which is preferably provided with perforations as shown. Located in the cylindrical or lower portionofthe part 21, of the casing, is the valve 24, for the mixing chamber, which valve is provided for the reception of the pump cylinder, and on each side of said opening with an opening 79, in which the u'pper ends of the rods 30, are secured, thus uniting the pump plunger 32, with said valve. vided near its periphery with a downwardly extended annular flange 80, in which is formed a series of openings 81, for the passage of air. Above the flange 80, the valve of inwardly in.- chned openings 82, which, when the'valve is raised, will afford communication between the lower portion of the casing and the mixing chamber 25, for the passage of air into resently explained. The f Awith a central opening 78, v

The valve 24, is prov the latter. Extended vertically through the wlth a cavity 85, extended from its .lower end upwardlylto a` suitable point, and has i movably tted therein aplung'er 32, which is extended through an opening in a` screw plug or cap 86, on the lower portion of the extension 83, of the casing. Leading from the upper end of the cavity 8,5, .in the pump cylinder is a channel 87, which terminates at its upper end in an enlarged opening 88,l

- end of the needle valve 67, which preferably has on its lower portion a collar 91, to deflect the gasolene as it 1s discharged from the pump. The valve seat 89, is provided with a series of Ichannels 92, which communicate with kthe enlarged opening 88, and said seat also has a tubular extension 93, in which is located a spring 94, to rest against a ball valve 95, which normally closes the channel 87, of the pump cylinder. Communicating with the opening 88, vand extended to one side thereof is a channel 96, which communicates with a channel 97 formed in the upper portion of the pump cylinder and 'extended downwardly therein to a point near the upper end of the cavity 85. The pump cylinder 84, is provided below the valve seat 23, with a lateral extension 98, which is located in a hollow lateral extension 99, on the lower portion 22, of thecasing and at one side of the extension 83, thereon; The extension 98, on the ump cylinder, -is provided with a screw t readed opening 100, in which is fit-ted a tubular piece 101, which is extended through an opening in the 'extension 99, and may be connected to a supply'of gasolene or hydrocarbon not shown. Leading from the lower end of the channel 97 through the extension 98, and into the opening in which the tube 101, is fitted, is a channel' 102.

Located in the upper end of the channelY 97, is a ball valve 103, which, is normally held so as to close the port 96, by means of a spring 104, located in the channel 97, and

resting at its lower. end on the lower surface ofthe channel 102, which as before stated communicates 'with the Isupply of gasolene. The lower portion of the extension 98, on the pump cylinder .is provided with a screw-threaded opening 105, in which is located a screw plug 106, which has in its upper portion a cavity 107 which has' com- .y munication through a channel 108, in the extension 98, with the cavity 85, of the pump cylinder. The cavity 107, .of the screw plug 106, also has communication-with the cavity of the tube 101, vthrough a channel 109, formed in said plug and the lower portion of the extension 98, of the pump cylinder. A ball valve 107 a, located in the cavity 107 is employed to open and close the port or channel 109, in the operation of the pump. y

Resting at one of its ends on the upper i surface of the valve 24, for the air chamber, is a spring '110, the other endV of which is seated against theupper portion of the part 21, of the/casing and normally holds said valve in its closed position. The extensiony 83, on the lower portion of the casing may be provided with a projection 111, having a cavity 112, in which is seated a spring 113, interposed between the head 114, `on thev upper end of a connecting rod 115, whichis extended through said 'project-ion and is pivotally secured atv its lower end toa lever 116, ulcrumed on the cap 86, and extended under the lower end of the pump plunger 32, as is clearly shown in Figs. 1, and 3, of the drawings. Fulcrum'ed on the lower portion of the part 21, of the casing, is a lever 117, theiinner end of which contacts with the 'upper .portion of the head 114, so that by raising the outer end of the lever 117 the lever-116, will be operated so as to irnpart motion to the plunger 32, and thus force gasolene into'the mixing chamber, which arrangement is designed to be used as an auxiliary means or for starting the operation Vof the carbureter.

From the foregoing and by reference tov the drawings, it will be clearly understood and readily seen that gasolene or otherhydrocarbons may be supplied to the pump through the member 101, which as before stated may have communication with a supply of gasolene or other hydrocarbon, and through the suction or operation of the engine the valve 24, of the. mixing chamber will be raised until the openings 81, are placed in communication with the lower portion of said chamben'at which timev air will pass through' the. openings or ports 82, and be discharged toward the upper end of the pump cylinder. In the upward movement of the valve 24, it is apparent that theplunger 32, being united thereto byy means of the rods 30, and bar 31, will be caused to rise in its cavity 'and thus force gasolene therefrom through the channel 87, opening 88, and the channels 92, in the valve seat 89, forthe needle valve. As soon as the suction in the mixing chamber ceases or is overcome, the spring 110,'will force said valve and plunger downwardly, in which operation gasolene will be drawn through the ports or said channels and back into the `inlettube 101, from which it will again be'v drawn into the pump. In order to regulate the quanf,

tities ofair and gasolene admitted to the mixing chamber, the lever 51, through its the screw 55, on the yoke-53, in which operation the yoke lwill be moved from the lneedle valve 67, for it` will be understood.

that said yoke is slidably mounted on the rod 44, t-hus causing the tapered portion 66, of the valve regulating rod 58, to be advanced under the lower end of the screw valve from its valve rod 73, which operation will raise the pin seat and permit an increased ainount of gasolene to be discharged into the mixing chamber. In the above delscribed operation, itis apparent that as the f arm 43, is rigidly connected to the .rod 44,

n arm 36, of the air later will be turned so as to cause its openj to the proper and said arm is adj ustably connected to the regulator, that said reguings 38, to register with theopenings 34, in the lower portion of the casing, thus permitting air to pass into the mixing chamber. As soon as ypressure has been removed from the lever 5l, it is evident that the .spring TO, acting-on the enlargement 65, of the valve regulating rod 58, willforce the same to its projected position, the limit of which maybe regulated by means of the adjusting screw 76, in the extension 63, on the fitting 6l, of the casing. By loosening the screw 41, and adjusting the sleeve nut 40, position wit-hin the slot 39, of the arm 36, and then tightening said screw, it is-obvious that the position of the air regulator''` may be ings 38, therein may completely or partially register with the openings 34, in the lower port-ion of the casing so as to admit a .larger or smaller quantity of air as desired.
